Flow Meter Symbol AutoCAD DWG Library: Accessing P&ID Instrument Icons for Engineers
Quick Answer: Flow meter symbols in AutoCAD DWG format help engineers build P&ID drawings faster. You can request ready made instrument icons for electromagnetic, Coriolis, vortex, oval gear, and thermal mass meters. Send us your pipe size, flow range, and process fluid to get matching symbol drawings and product datasheets.
Why P&ID Flow Meter Symbols Matter
In a P&ID, the flow meter symbol tells the installer and operator what type of instrument sits on the pipe. The symbol shape alone does not show the model, but it defines the measuring principle. For example, a circle with a line through it may represent an inline flow element. A square with a circle inside may represent a mass flow meter. Engineers in water treatment plants, chemical dosing systems, and fuel oil transfer lines use these symbols every week.
Here is the thing. Most engineers skip the symbol library step. They redraw each instrument icon from scratch. That takes time and creates drawing errors. A clean DWG block avoids this problem.
What You Get in an AutoCAD DWG Library
Most flow meter symbol libraries come as DWG files. Each block includes the instrument bubble, tag number placeholder, and line connection points. You can drop these blocks into P&ID drawings without redrawing the symbol from scratch.
Silver Instruments provides DWG blocks for common meter types when you ask for a quote. We have seen customers in Vietnam and Nigeria build detailed P&ID packages for water and diesel lines using these blocks. The blocks work in AutoCAD 2018 and newer versions. They also open in compatible CAD applications.
Common Flow Meter Symbols in P&ID Packages
Electromagnetic flow meter symbols often show a round body with two coils. Coriolis mass flow meter symbols use two parallel tubes or a U shape. Vortex flow meter symbols show a bluff body inside the pipe. Oval gear meter symbols show two interlocking oval rotors. Thermal mass flow meter symbols often show a probe inside a pipe.
Each block carries a tag name and a signal output note such as 4-20 mA HART or pulse. You can also add a PT100 reference for temperature compensation on gas flow drawings. A food grade application with viscosity up to 1000 cP needs an oval gear meter symbol with pulse output. The Silver Instruments OGF series covers this application. A gas flow application at 50 kg/h needs a thermal mass meter symbol with 4-20 mA output. The Silver Instruments TMF 100 series has a probe style symbol.

A wastewater plant in the Philippines uses electromagnetic flow meters on lines with conductivity above 20 µS/cm. These meters need a simple inline symbol in the P&ID. We also supplied a 4-20 mA HART signal note on the tag.
Silver Instruments P&ID and Product Support
Silver Automation Instruments supplies flow meters and pressure transmitters for Southeast Asia, Oceania, Latin America, Africa, and the Middle East. Our product range includes Coriolis mass flow meters, electromagnetic flow meters, ultrasonic flow meters, vortex flow meters, oval gear flow meters, thermal mass flow meters, pressure transmitters, and paperless recorders.
Many customers need symbols for ATEX Zone 1 areas or high temperature processes up to 180 degrees Celsius. We provide the DWG blocks and the instrument datasheets together. For a DN15 chemical dosing line, we recommend the Silver Instruments OGF 15 series oval gear meter. The DWG block for this meter is small and fits tight P&ID drawings.
Frequently Asked Questions
Can I get flow meter symbols in AutoCAD DWG format from Silver Instruments? Yes. Ask our team for the DWG block library. We send symbols for all meter types along with a product quote.
Which flow meter symbol standards do you follow? We follow ISA 5.1 and ISO 10628 style conventions. The blocks are clean and easy to edit in AutoCAD.
Do you include signal details on the P&ID symbols? Yes. You can note 4-20 mA HART, pulse output, or RS485 on the symbol tag. We add the instrument tag number as a text attribute.
What if our pipe size is DN15 or smaller? We can supply symbols and meters for DN15, DN25, DN40, DN50, DN80, DN100, DN150, DN200, DN300, and above. Small line sizes are common for chemical dosing and pilot plants.
How fast can we get the DWG library? Most requests are answered within 24 hours. If you send process data in the first message, we can include matching product models and price on the same day.
